A stone is shot straight upward with a speed of 20 m/sec from a tower 200 m high. The speed with which it strikes the ground is approximately

A body freely falling from the rest has a velocity \'v\' after it falls through a height \'h\'. The distance it has to fall down for its velocity to become double, is

A body thrown vertically upwards with an initial velocity u reaches maximum height in 6 sec. he ratio of the distances travelled by the body in the first second and the seventh second is

A body thrown upwards with some velocity, reaches the maximum height of 20 m. Another body with double the mass thrown up, with double initial velocity will reach a maximum height of

A balloon starts rising from the ground with an acceleration of 1.25 ms² after 8s, a stone is released from the balloon. The stone will (g = 10 ms²)

A body is thrown vertically upwards with a velocity u. Fins the true statement from the following

A man throws a ball vertically upward and it rises through 20 m and returns to his hands. What was the initial velocity (u) of the ball and for how much time (T) it remained in the air (g = 10 m/s²)

A particle when thrown, moves such that it passes from same height at 2 and 10 s, the height is

Two balls A and B of same masses are thrown from the top of the building. A, thrown upwards with velocity V and B, thrown downward with velocity V, then

A ball is dropped from top of a tower of 100 m height. Simultaneously another ball was thrown upward from bottom od the tower with a speed of 50 m/s (g = 10 m/s²) . They will cross each other
